What EV Charger Do You Need for a 2023 BMW i4 eDrive35 Gran Coupe?
Buying an 80-amp charger for this BMW wastes money on capacity the car will never touch. The vehicle draws up to 48 amps on a Level 2 circuit. Match that ceiling and nothing higher.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 6.9 hours |
| Range added per hour (Level 2) | about 37 miles |
| Full charge on a 120 V outlet | about 53 hours |
| Range added per hour (120 V) | about 4.8 miles |
| EPA rated range | 256 miles |
| Energy for a full charge | about 76.4 kWh at the wall |
Why 48 amps and not more
The 2023 BMW i4 eDrive35 Gran Coupe handles 48 amps through its 11.0 kW onboard charger. Hooking it to a larger supply changes nothing because the car limits the current internally. Pushing past 48 amps buys you zero speed. It only adds heat and cost. Stick to the specified rating and fill the 76.4 kWh battery from empty in 6.9 hours.
What the install involves
Feed your 48-amp Level 2 unit with a 60-amp circuit breaker. Hardwiring is mandatory here since no standard household receptacle handles a continuous 48-amp load safely. Copper wire size matters for this amperage draw. Hire a licensed electrician to run the line and mount the gear.

Common questions
- What connector does this car use?
- It uses a J1772 connector for standard Level 2 charging. Every non-Tesla EV sold in North America through 2024 uses this port.
- Can I plug this into a regular wall outlet?
- Level 1 charging uses a standard household outlet and takes 53 hours for a full charge. That yields 4.8 miles of range per hour.
- Why does the EPA charge time differ?
- The EPA lists an 8.0-hour charge time because government test cycles do not always run at the car's peak AC rate. Real-world maximum Level 2 speed finishes the job in 6.9 hours.
- How much range do I get per hour on Level 2?
- You add 37 miles of range for every hour connected to a max-rate Level 2 supply. The EPA rating calculates to 32 miles per hour.
Other vehicles
Charging times derived from EPA data for the 2023 BMW i4 eDrive35 Gran Coupe (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
